34. A major department store chain is interested in estimating the mean amount its credit card customers spent on their first visit to the chain's new store in the mall. Fifteen credit card accounts were randomly sampled and analyzed with the following results: mean of the sample is $50.50 and S=20. Construct a 95% confidence interval for the mean amount its credit card customers spent on their first visit to the chain's new store in the mall assuming that the amount spent follows a normal distribution. *m (1 Point) $50.50 + $9.09 550.50 = $10.12 550.50 $11.00 $50.50 + $11.08
